<h4>Feedback Collection</h4>
TaxDebug collects optional feedback to improve the plugin:
<ul>
<li>In-app feedback: Report false positives, false negatives, feature requests, or success stories</li>
<li>Usage analytics: Anonymous local tracking of which features are used</li>
<li>Deactivation survey: Optional one-question survey when deactivating</li>
</ul>
Local Storage: All feedback is always stored locally in your WordPress database.
Optional Remote Sending: You can opt-in to send anonymous feedback to the developer to help improve TaxDebug. This is disabled by default and must be explicitly enabled in Settings.
<h4>What IS Sent (When Opted-In)</h4>
<ul>
<li>Anonymous store UUID (random identifier, NOT your domain)</li>
<li>Feedback type and message</li>
<li>Your email (only if you voluntarily provide it)</li>
<li>Store country and currency</li>
<li>Active tax plugin (e.g., TaxJar, Avalara)</li>
<li>Plugin, WordPress, and WooCommerce versions</li>
<li>Daily aggregated counts: orders logged, issues detected, features used</li>
</ul>
<h4>What is NEVER Sent</h4>
<ul>
<li>Your site URL or domain name</li>
<li>Customer names, emails, or addresses</li>
<li>Order details, totals, or line items</li>
<li>Tax amounts or financial data</li>
<li>Any personally identifiable information (PII)</li>
</ul>
<h4>How to Disable Remote Sending</h4>
Go to WooCommerce → TaxDebug → Settings and turn off “Send Anonymous Feedback”. You can do this at any time. Local feedback storage will continue to work.
